These geometric ball bookends are seriously stylish! Made from solid cast iron, each bookend weighs 2.4 pounds (1.1kg) - heavy enough to securely hold your books in place without tipping over. Measuring 5.1 inches wide and 4.3 inches tall, they have that modern ambipolar design that looks amazing on any shelf. The black finish is neutral enough to fit with any decor style - whether your place is modern, industrial, or traditional. They include 6 anti-slip stickers to prevent scratching your furniture and keep them from sliding on smooth surfaces. Beyond just holding books, you can use them as paperweights, decorative accents, or even door holders. The craftsmanship is impressive - the cast iron feels substantial and well-made, not cheap or flimsy. Much nicer than plastic bookends that break easily or don't have enough weight. Perfect for organizing your book collection while adding some artistic flair to your space. Works great in home offices, living rooms, bedrooms, or even commercial spaces like cafes. The geometric ball design is so unique compared to basic rectangular bookends. They arrive as a set of two, ready to display immediately. The weight distribution is perfect - they stand solidly without being too heavy to move around. Whether you're a book lover or just want to upgrade your shelf game, these bookends deliver both function and serious style points. Your bookshelf will look so much more organized and intentional with these holding everything in place!
